Detailed Description

template<class Particle>
class HeatFluidCoupled< Particle >

Class of particles that store both temperature and liquid volume, which is adapted for the CFD-DEM studies.

In some CFD-DEM studies, a drying process needs to be simulated. Therefore, we selected the drying/liquid evaporation model of Azmir et al. (2018), which considers heat and mass transfer between the liquid film on the particles and the surrounding air. Their model considers convection, conduction, radiation of heat, and evaporation of liquid. Conduction is already implemented in ThermalParticles, from which this class derives; convection and radiation is still missing. This class implements evaporation model.

Constructor & Destructor Documentation

HeatFluidCoupled() [1/2]

template<class Particle >

HeatFluidCoupled< Particle >::HeatFluidCoupled ( )

default

HeatFluidCoupled constructor creates a HeatFluidCoupled at (0,0,0) with radius, mass and inertia equal to 1.

HeatFluidCoupled() [2/2]

template<class Particle >

HeatFluidCoupled< Particle >::HeatFluidCoupled ( const HeatFluidCoupled< Particle > &  p )

default

HeatFluidCoupled copy constructor, which accepts as input a reference to a HeatFluidCoupled. It creates a copy of this HeatFluidCoupled and all it's information. Usually it is better to use the copy() function for polymorphism.

Constructor that copies most of the properties of the given particle. Please note that not everything is copied, for example the position in the HGrid is not determined yet by the end of this constructor. It also does not copy the interactions and the pointer to the handler that handles this particle. Use with care.

Parameters

[in,out]

p

Reference to the HeatFluidCoupled this one should become a copy of.

~HeatFluidCoupled()

template<class Particle >

HeatFluidCoupled< Particle >::~HeatFluidCoupled ( )

overridedefault

HeatFluidCoupled destructor, needs to be implemented and checked if it removes tangential spring information.

Destructor that asks the ParticleHandler to check if this was the smallest or largest particle and adjust itself accordingly.

Member Function Documentation

actionsAfterTimeStep()

template<class Particle >

void HeatFluidCoupled< Particle >::actionsAfterTimeStep ( )

inlineoverride

The actionAfterTimeStep is defined in the species, as we cannot extract the species properties of a HeatFluidCoupled*Species.

                                         {
        this->getSpecies()->actionsAfterTimeStep(this);
    }

copy()

template<class Particle >

HeatFluidCoupled* HeatFluidCoupled< Particle >::copy ( ) const

inlineoverride

HeatFluidCoupled copy method. Use copy constructor of this HeatFluidCoupled to create a copy on the heap, useful for polymorphism.

Returns

pointer to the particle's copy.

    {
        return new HeatFluidCoupled<Particle>(*this);
    }

getFieldVTK()

template<class Particle >

std::vector<Mdouble> HeatFluidCoupled< Particle >::getFieldVTK ( unsigned  i ) const

inlineoverride

Tells the vtkWriter the value of each field written for this particle type.

                                                              {
        if (i==0)
            return { this->getFullLiquidVolume() };
        else if (i==1)
            return { this->liquidVolume_ };
        else if (i==2)
            return { this->getLiquidBridgeVolume() };
        else if (i==3)
            return { this->totalEvaporatedLiquidVolume_ };
